What is the process of translocation in phloem?

Phloem consists of living cells arranged end to end. Phloem transports sucrose and amino acids up and down the plant. This is called translocation . In general, this happens between where these substances are made (the sources) and where they are used or stored (the sinks).

What is the translocation process?

The movement of sucrose and other substances like amino acids around a plant is called translocation . In general, this happens between where these substances are made (the sources) and where they are used or stored (the sinks): from sources in the root to sinks in the leaves in early spring time.

What is the word phloem?

Phloem, also called bast, tissues in plants that conduct foods made in the leaves to all other parts of the plant. Phloem is composed of various specialized cells called sieve tubes, companion cells, phloem fibres, and phloem parenchyma cells.

How does the phloem work?

The phloem carries important sugars, organic compounds, and minerals around a plant. Sap within the phloem simply travels by diffusion between cells and works its way from leaves down to the roots with help from gravity. The phloem is made from cells called ‘sieve-tube members’ and ‘companion cells’.

What transports phloem?

Phloem transports carbohydrates, produced by photosynthesis and hydrolysis of reserve compounds, to sink tissues for growth, respiration and storage.

What is translocation answer?

Answer: Translocation is a biological mechanism involving the transfer of water and other soluble nutrients from one part of the plant to another through the xylem and phloem, which occurs in all plants.

What happens before translocation?

EF-G binding to the pre-translocation ribosome stabilizes the ratchet/hybrid conformation; the tRNA anticodons do not move at this stage. GTP hydrolysis accelerates a rearrangement of the ribosome (frequently referred to as “unlocking”) that precedes and limits the rate of tRNA-mRNA movement on the 30S subunit.

What is phloem give an example?

Phloem is the tissue in plants that transport food to the parts of the plant where it needs to go. An example of the phloem is the tissue in plants that distributes the sugar that plants eat. Phloem consists of several different kinds of cells: sieve elements, parenchyma cells, sclereids, and fibers.

Where is phloem found?

Answer: Phloem tissues are found in the leaves or other parts of the plant to conduct food materials.

What are the characteristics of phloem?

The presence of a variety of elements is characteristic of phloem in view of its many functions: sieve elements, storage and crystal-containing phloem parenchyma cells, phloem (bast) fibers and sclereids, and radial parenchyma of medullary rays. In some plants, the phloem has latex vessels and resin ducts.

Where is the phloem located?

In trees and other woody plants, the phloem is found in the innermost layer of the tree’s bark.

What is an example of phloem?

Illustration of leaf anatomy. noun. Phloem is the tissue in plants that transport food to the parts of the plant where it needs to go. An example of the phloem is the tissue in plants that distributes the sugar that plants eat. YourDictionary definition and usage example.

What is the function of phloem in a plant cell?

amino acids etc.

  • It can also help in the transportation of proteins and mRNAs.
  • The sieve tubes of phloem give strength to the plant against cell bursting.
  • Sieve plate allows the continuous movement of sap through the sieve pores both in a forward and backward direction that keeps the cell hydrated.
